Objective: The aim: Assessment of the effectiveness of using minimally invasive and open methods of bile duct decompression for treatment of obstructive jaundice (OJ) by comparing complications in patients of di!erent age groups.
Patients And Methods: Materials and methods: We analyzed the results of surgical treatment of 250 patients with OJ. The patients were assigned to two groups: Group I (n = 100) consisting of young and middle-age patients, and Group II (n = 150) consisting of elderly, senile and long-living patients.
Article Synopsis
- The grey wolf was the first animal to be domesticated into dogs and lived through the last Ice Age when many other animals went extinct.
- Scientists studied 72 ancient wolf genomes from different places to understand how wolves were connected and how they evolved over 100,000 years.
- They found that dogs are more closely related to ancient wolves from eastern Asia, but some dogs in the Near East and Africa share ancestors with different wolves, which means there might have been several ways dogs were domesticated.
The cave lion is an extinct felid that was widespread across the Holarctic throughout the Late Pleistocene. Its closest extant relative is the lion (Panthera leo), but the timing of the divergence between these two taxa, as well as their taxonomic ranking are contentious. In this study we analyse 31 mitochondrial genome sequences from cave lion individuals that, through a combination of C and genetic tip dating, are estimated to be from dates extending well into the mid-Pleistocene.

Consequences of past climate change and recent human persecution on mitogenomic diversity in the arctic fox.
Philos Trans R Soc Lond B Biol Sci

Ancient DNA provides a powerful means to investigate the timing, rate and extent of population declines caused by extrinsic factors, such as past climate change and human activities. One species probably affected by both these factors is the arctic fox, which had a large distribution during the last glaciation that subsequently contracted at the start of the Holocene. More recently, the arctic fox population in Scandinavia went through a demographic bottleneck owing to human persecution.
